cannot get values from a php array

Question

This is my php code

 echo '<pre>';
 print_r($weekdays); echo '<br/>';

 foreach ($weekdays as $key => $day) {

     print_r($day); echo '<br/>';
     echo 'key - '. $key; echo '<br/>';
     echo 'val - '. $day['val']; die;      
 }

This is result of this

Array
(
[sunday] => Array
    (
        ['val'] => 1
        ['from'] => 6:00:00
        ['to'] => 6:00:00
    )

The problem is that the key isn't val it's 'val' (with the quotes).

echo 'val - '. $day["'val'"];

Will work.

It appears that your key is actually 'val', not val.

I suppose It would be best to make sure you do not name array keys with apostrophes. This might confuse you in the future or whoever works on this code.

Your print_r should look like this:

Array ( 
    [sunday] => Array
       (
          [val] => 1
          [from] => 6:00:00
          [to] => 6:00:00
       )

Correct the code that creates that array and you will be set.
